Chelsea youngster Lucas Piazon has thrown his long-term future at Stamford Bridge into doubt after claiming his efforts on loan at Eintracht Frankfurt are with a view of playing for a new club in the future.

Piazon has spent the last three seasons on loan at Malaga, Vitesse Arnhem and Eintracht as his opportunities in west London continue to dwindle, with his last Blues appearance having come in December 2012.

The 20-year-old has watched on as Thibaut Courtois, who spent three years on loan at Atletico Madrid, has claimed an automatic starting place upon his return to Chelsea and Piazon is targeting the chance to make a similar impact.

However, the player has hinted his future could yet lie away from Chelsea, having seen the likes of Cesc Fabregas, Willian and Mohamed Salah join the club in the past 12 months.

"At the moment I'm sitting on the bench [with Eintracht], so it's difficult to make an impression," he told Goal.com. "I'll keep on working to play for Chelsea or some other club in the future.

"It's different with him [Courtois], he has already made a name for himself and played for Atletico, a big club in Europe. I'm much younger and have to try to do a good job. When I can't play for Chelsea, then for another club.

"In the Netherlands [with Vitesse] we were in the title race for a long time. In Spain I had a great time, because we played in the Champions League with Malaga.

"So I can't complain, these clubs helped me a lot and, I hope, this year in Frankfurt will help me develop further."

Since re-joining the club, Chelsea manager Jose Mourinho has committed to supplementing his squad with more players from the club's academy, saying he will blame himself should no products from the system graduate to the first team.
